My PAYG sim has been locked for a second time, first time I managed to get it sorted with £9+ credit, a few weeks after that, it was locked again... I only use it for emergencies. I needed to use it just before lockdown 7 weeks ago... tried to get in touch with o2 but no luck because of Coronavirus.
The number I need to get unlocked is different to the one I am registered with. Please advise, thank you.
